dual print issue with flashforge dreamer

Hi guys,

I had a dual print problem using pla and pva with my dreamer. As shown in the video, the pva (on right nozzle) just kept coming out when printing pla (on left nozzle). I would like to know how to fix this problem?

Thanks a lot

What temperatures are you using and other settings are you using? What slicer?

Maybe the PVA temp is too high and its oozing out.

Need more information before we can help you.
